  • How to get feedback on mobile application

    - by Jason Crosby
    I am relatively new to programming. I have been programming with Java and Android for about 2 years now and just recently released my first app to the Google Play app store. I have passed the word on to everyone I know and posted a few times on Facebook about it. But I am not really seeing anyone install them. I love to code I'm not looking to have the next big time app, but it would be nice to get some installs and feedback/ratings so I can get an idea of how well its doing and if there are any fixes or improvements I can make. I thought about doing an AdMob campaign a couple times here and there at about $10 to $20 per day. But I'm not sure if that will generate any kind of worthwhile feedback. What other things could I be doing in order to get some feedback on my application? Thanks in advance for your help and suggestions.

  • How can I port forward with an airport extreme and a NAT enabled modem?

    - by Jon
    I run an Actiontec HD701D modem with NAT to an Airport extreme base station to laptop etc. As you might expect I get double NAT issues. I tried a lot of different things to forward a port, but no luck. Currently the airport is in bridge mode letting the modem handle the NAT, but still can't forward the port. Also to note: firewall is off on the router, firewall is set to allow the application in OSX 10.6.3 and I did forward the port in the router. No luck.

  • Game testing on Android - emulator or real devices?

    - by n00bfuscator
    I am working at a localization agency and we have been approached by a client about testing their games on iOS as well as Android. Testing on iOS seems fairly easy as we can just buy a couple of devices and we should be covered. For Android it seems to be completely different. From what i found, the emulator can cover all API levels, screen sizes and such, but i hear it's buggy and nothing could replace testing on real devices. With the vast amount of Android devices out there and the rate at which new devices are released it seems impossible to keep up. How can i test games (localization and functional) on Android covering all compatible devices?

  • Writing files to an Airport Extreme using afp

    - by Bill Oldroyd
    Using Nautilus I can connect from Ubuntu 12.04 (64-bit) to my Apple Airport Extreme using user & password without a problem. I can read, browse folders and delete files. However I cannot write files, the file is created, but the contents of the file are not transferred. The transfer fails with the error message "kFPMiscErr" which I think means that "authentication has already been established" ?. I have tried the command line tools for access using AFP but these do not work either. Is there a solution to this problem ?

  • Network and Storage Devices Throughput Chart

    - by zroiy
    With all of the different storage and network devices that surround our day to day life, understanding these devices data transfer speeds can be somewhat confusing. Think about trying to identify your weakest link in the a chain that starts with an external USB hard drive (or a flash drive) that's connected to a 802.11g wifi router, can you quickly come up with an answer of where's the bottle neck in that chain , is it the router or the storage devices ? . Well, the following chart should give you an idea understanding different devices, protocols and interfaces maximum throughput speeds. Though these numbers can fluctuate (mostly for worse, but sometimes for the better) due to different kind of factors such as OS overhead (or caching and optimization) , multiple users or processes and so on , the chart can still serve to provide basic information on the theoretical throughput different devices and protocols can get to.. Enjoy.  Link to the full size chart   References:http://en.wikipedia.org/wiki/Sata#SATA_revision_1.0_.28SATA_1.5_Gbit.2Fs.29http://en.wikipedia.org/wiki/Usbhttp://en.wikipedia.org/wiki/Usb_3http://en.wikipedia.org/wiki/802.11http://mashable.com/2011/09/21/fastest-download-speeds-infographic/http://en.wikipedia.org/wiki/Thunderbolt_(interface)http://www.computerworld.com/s/article/9220434/Thunderbolt_vs._SuperSpeed_USB_3.0  Icons:http://openiconlibrary.sourceforge.net/gallery2/?./Icons/devices/drive-harddisk-3.png

  • 50 Billion Served: Java Embedded on Devices

    - by Tori Wieldt
    It doesn't matter if it is 50 billion or 24 billion, just suffice it to stay that there will be MANY connected devices in the year 2020. With just 24 billion devices, they will outnumber humans six to one! So as a developer, you don't want to ignore this opportunity. What if you could use your Java skills and deploy an app to a fraction of these devices (don't be greedy, how about just, say, 118,000 of them)? Fareed Suliman, Java ME Product Manager had lots of good news for Java Developers in his presentation Modernizing the Explosion of Advanced Microcontrollers with Embedded Java at ARM TechCon in Santa Clara, CA last week. "A radical architecture shift is underway in this space, from proprietary to standards-based," he explained.  He pointed out several advantages to using Embedded Java for devices: Java is a proven and open standard. Java provides connectivity, encryption, location, and web services APIs. You don't have to focus on and keep reinventing the plumbing below the JVM. Abstracting the software from the hardware allows you to repeat your app across many devices. Abstracting the software from the hardware allows allows parallel development so you can get your app done more quickly. You already know Java (or you can hire lots of Java talent). Java is a full ecosystem, with Java Embedded plugins for IDEs like Eclipse and NetBeans. Java ME allows for in-field software upgrades. Suliman mentioned two ways developers can start using Java Embedded today:  Java ME Embedded Suite 7.0 Oracle Java Embedded Suite is a new packaged solution from Oracle (including Java DB, GlassFish for Embedded Suite, Jersey Web Services Framework, and Oracle Java SE Embedded 7 platform), created to provide value added services for collecting, managing, and transmitting data to embedded devices such as gateways and concentrators. Oracle Java ME Embedded 3.2 Oracle Java ME Embedded 3.2 is designed and optimized to meet the unique requirements of small embedded, low power devices such as micro-controllers and other resource-constrained hardware without screens or user interfaces. Think tiny. Really tiny. And think big.  Read more about Java Embedded at the Oracle Technology Network, and read The Java Source blog Java Embedded Releases from September.

  • SQLAuthority News – Amazon Gift Card Raffle for Beta Tester Feedback for NuoDB

    - by pinaldave
    As regular readers know I’ve been spending some time working with the NuoDB beta software. They contacted me last week and asked if I would give you a chance to try their new web-based console for their scalable, SQL-compliant database. They have just put out their final beta release, Beta 9.  It contains a preview of a new web-based “NuoConsole” that will replace and extend the functionality of their current desktop version.  I haven’t spent any time with the new console yet but a really quick look tells me it should make it easier to do deeper monitoring than the older one. It also looks like they have added query-level reporting through the console. I will try to play with it soon. NuoDB is doing a last, big push to get some more feedback from developers before they release their 1.0 product sometime in the next several weeks. Since the console is new, they are especially interested in some quick feedback on it before general availability. For SQLAuthority readers only, NuoDB will raffle off three $50 Amazon gift cards in exchange for your feedback on the NuoConsole preview. Here’s how to Enter Download NuoDBeta 9 here You must build a domain before you can start the console. Launch the Web Console. Windows Code: start java -jar jarnuodbwebconsole.jar Mac, Linux, Solaris, Unix Code: java -jar jar/nuodbwebconsole.jar Access the Web Console: Code: http://localhost:8080 When you have tried it out, go to a short (8 question) survey to enter the raffle Click here for the survey You must complete the survey before midnight EDT on October 17, 2012. Here’s what else they are saying about this last beta before general availability: Beta 9 now supports the Zend PHP framework so that PHP developers can directly integrate web applications with NuoDB. Multi-threaded HDFS support – NuoDB Storage Managers can now be configured to persist data to the high performance Hadoop distributed file system (HDFS). Beta 9 optimizes for multi-thread I/O streams at maximum performance. This enhancement allows users to make Hadoop their core storage with no extra effort which is a pretty cool idea. Improved Performance –On a single transaction node, Beta 9 offers performance comparable with MySQL and MariaDB. As additional nodes are added, NuoDB performance improves significantly at near linear scale. Query & Explain Plan Logging – Beta 9 introduces SQL explain plans for your queries. Qualify queries with the word “EXPLAIN” and NuoDB will respond with the details of the execution plan allowing performance optimization to SQL. Through the NuoConsole, you can now kill hung or long running queries. Java App Server Support – Beta 9 now supports leading Web JEE app servers including JBoss, Tomcat, and ColdFusion. They’ve also reported: Improved PHP/PDO drivers Support for Drupal Faster Ruby on Rails driver The Hibernate Dialect supports version 4.1 And good news for my readers: numerous SQL enhancements They will share the results of the web console feedback with me.  I’ll let you know how it goes. Also the winner of their last contest was Jaime Martínez Lafargue!  Do leave a comment here once you complete the survey.  Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: SQL Authority Tagged: NuoDB

  • Java Champion Jorge Vargas on Extreme Programming, Geolocalization, and Latin American Programmers

    - by Janice J. Heiss
    In a new interview, up on otn/java, titled “An Interview with Java Champion Jorge Vargas,” Jorge Vargas, a leading Mexican developer, discusses the process of introducing companies to Enterprise JavaBeans through the application of Extreme Programming. Among other things, he gives workshops about building code with agile techniques and creates a master project to build all apps based on Scrum, XP methods and Kanban. He focuses on building core components such as security, login, and menus. Vargas remarks, “This may sound easy, but it’s not—the process takes months and hundreds of hours, but it can be controlled, and with small iterations, we can translate customer requirements and problems of legacy systems to the new system.” In regard to his work with geolocalization, he says: “We have launched a beta program of Yumbling, a geolocalization-based app, with mobile clients for BlackBerry, iPhone, Android, and Nokia, with a Web interface. The first challenge was to design a simple universal mechanism providing information to all clients and to minimize maintenance provision to them. I try not to generalize a lot—to avoid low performance or misunderstanding in processing data. We use the latest Java EE technology—during the last five years, I’ve taught people how to use Java EE efficiently.” Check out the interview here.

  • Extreme Optimization – Curves (Function Mapping) Part 1

    - by JoshReuben
    Overview ·        a curve is a functional map relationship between two factors (i.e. a function - However, the word function is a reserved word). ·        You can use the EO API to create common types of functions, find zeroes and calculate derivatives - currently supports constants, lines, quadratic curves, polynomials and Chebyshev approximations. ·        A function basis is a set of functions that can be combined to form a particular class of functions.   The Curve class ·        the abstract base class from which all other curve classes are derived – it provides the following methods: ·        ValueAt(Double) - evaluates the curve at a specific point. ·        SlopeAt(Double) - evaluates the derivative ·        Integral(Double, Double) - evaluates the definite integral over a specified interval. ·        TangentAt(Double) - returns a Line curve that is the tangent to the curve at a specific point. ·        FindRoots() - attempts to find all the roots or zeroes of the curve. ·        A particular type of curve is defined by a Parameters property, of type ParameterCollection   The GeneralCurve class ·        defines a curve whose value and, optionally, derivative and integrals, are calculated using arbitrary methods. A general curve has no parameters. ·        Constructor params:  RealFunction delegates – 1 for the function, and optionally another 2 for the derivative and integral ·        If no derivative  or integral function is supplied, they are calculated via the NumericalDifferentiation  and AdaptiveIntegrator classes in the Extreme.Mathematics.Calculus namespace. // the function is 1/(1+x^2) private double f(double x) {     return 1 / (1 + x*x); }   // Its derivative is -2x/(1+x^2)^2 private double df(double x) {     double y = 1 + x*x;     return -2*x* / (y*y); }   // The integral of f is Arctan(x), which is available from the Math class. var c1 = new GeneralCurve (new RealFunction(f), new RealFunction(df), new RealFunction(System.Math.Atan)); // Find the tangent to this curve at x=1 (the Line class is derived from Curve) Line l1 = c1.TangentAt(1);

  • The Connected Company: WebCenter Portal - Feedback - Analytics and Polls

    - by Michael Snow
    Evernote Export body, td { }Guest Post by: Mitchell Palski, Staff Sales Consultant The importance of connecting peers has been widely recognized and socialized as a critical component of employee intranets. Organizations are striving to provide mediums for sharing knowledge and improving awareness across their enterprise. Indirectly, the socialization of your enterprise should lead to cost savings and improved product/service quality. However, many times the direct effects of connecting an organization’s leadership with its employees are overlooked. Oracle WebCenter Portal can help you bridge that gap by gathering implicit and explicit feedback. Implicit Feedback Through Usage Analytics Analytics allows administrators to track and analyze WebCenter Portal traffic and usage. Analytics provides the following basic functionality: Usage Tracking Metrics: Analytics collects and reports metrics of common WebCenter Portal functions, including community and portlet traffic. Behavior Tracking: Analytics can be used to analyze WebCenter Portal metrics to determine usage patterns, such as page visit duration and usage over time. User Profile Correlation: Analytics can be used to correlate metric information with user profile information. Usage tracking reports can be viewed and filtered by user profile data such as country, company or title. Usage analytics help measure how users interact with website content – allowing your IT staff and business analysts to make informed decisions when planning development for your next intranet enhancement. For example: If users are not accessing your Announcements page and missing critical information that they need to be aware of, you may elect to use graphical links on the home page to direct more users to that page. As a result, the number of employee help-requests to HR decreases. If users are not accessing your News page to read recent articles, you may elect to stop spending as much time updating the page with new stories and cut costs in your communications department. You notice that there is a high volume of users accessing the Employee Dashboard page so your organization decides to continue making personalization enhancements to the page and investing in the Portal tool that most users are accessing. Usage analytics aren’t necessarily a new concept in the IT industry. What sets WebCenter Portal Analytics apart is: Reports are tailored for WebCenter specific tools Report can be easily added to a page as simple as a drag-and-drop Explicit Feedback Through Polls WebCenter Portal users can create, edit, take, and analyze online polls. With polls, you can survey your audience (such as their opinions and their experience level), check whether they can recall important information, and gather feedback and metrics. How many times have you been involved in a requirements discussion and someone has asked a question similar to “Well how do you know that no one likes our home page?” and the response is “Everyone says they hate it! That’s all anyone complains about.” No one has any measurable, quantifiable metric to gauge user satisfaction. Analytics measure usage, but your organization also needs to measure the quality of your portal as defined by the actual people that use it. With that information, your leadership can make informed decisions that will not only match usage patterns but also relate to employees on a personal level. The end result is a connection between employees and leadership that gives everyone in the organization a sense of ownership of their Portal rather than the feeling of development decisions being segregated to leadership only. Polls can be created and edited through the Poll Manager: Polls and View Poll Results can easily be added to a page through drag-and-drop. What did we learn? Being a “connected” company doesn’t just mean helping employees connect with each other horizontally across your enterprise. It also means connecting those employees to the decisions that affect their everyday activities. Through WebCenter Portal Usage Analytics and Polls, any decision that is made to remove a Portal page, update a Portal page, or develop new Portal functionality, can be justified by quantifiable metrics. Instead of fielding complaints and hearing that your employees don’t have a voice, give those employees a voice and listen!

  • How important is positive feedback in code reviews?

    - by c_maker
    Is it important to point out the good parts of the code during a code review and the reasons why it is good? Positive feedback might be just as useful for the developer being reviewed and for the others that participate in the review. We are doing reviews using an online tool, so developers can open reviews for their committed code and others can review their code within a given time period (e.g. 1 week). Others can comment on the code or other reviewer's comments. Should there be a balance between positive and negative feedback?

  • How to get useful feedback/bug reports from users

    - by Mikael Eliasson
    I'm sure most webmasters have recived a mail like this: Creating [insert item here] is not working! When you check it out there is no general problem with the function but rather the user has discovered an edge case. Almost every mail I get is like this and in the long run it gets a bit annoying to always have to ask the user for more information. Is there anything I can do to get my users provide more useful feedback? Right now I have a mailto: for the webmaster mail in the page footer. I was thinking of changing this so that they have to report through a form on the site. Anyone got any experience with this? Do you get better/more reports by having a feedback form instead of giving the users the email?

  • Providing feedback on the Solaris Studio 12.4 Beta

    - by Darryl Gove
    Obviously, the point of the Solaris Studio 12.4 Beta programme was for everyone to try out the new version of the compiler and tools, and for us to gather feedback on what was working, what was broken, and what was missing. We've had lots of useful feedback - you can see some of it on the forums. But we're after more. Hence we have a Solaris Studio 12.4 Beta survey where you can tell us more about your experiences. Your comments are really helpful to us. Thanks.

  • Software engineering project idea feedback [on hold]

    - by Chris Sewell
    I'm a third year student currently undergoing my project/dissertation section of my degree. I have drafted a proposal for my final year project and would appreciate any feedback. The feedback can be anything constructive either specific to this proposal, the area that I will be working and researching in or my ideas. I will accept all input. Aims My aim is to attempt a proof of concept and prototype a runtime-as-a-service (RaaS). This cloud based runtime will allow clients to dynamically offload tasks or create cloud applications. Currently software-as-a-service (SaaS) cloud applications are purpose built and have a predefined scope in which they can assist or serve the client; this scope cannot be changed without physical alteration to the client and server software. With RaaS the client potentially could define any task it wanted at any time depending on its environment variables, the client and server would then communicate parameters and returns for that task. For the client to utilize a RaaS it must be able to conceive and then define a task using an appropriate XML vocabulary. As the scope of the cloud solution is defined by the client at its runtime, the cloud solution only has to exist for as long as the client requires it to as opposed to a client using a dedicated service. Deliverables The crux of the project will require an XML vocabulary in which the client and server will communicate. I’ll prototype the server application that will dynamically create and manage cloud solutions. The solution will be coded using an interpreted language, such as python or javascript, which can evaluate expressions in runtime or a language that can dynamically compile such as C# or Java. As a further proof of concept I will also produce a mock client that offloads tasks to the server. The report will attempt to explain the different flavours of cloud computing solutions including infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and SaaS including real world examples and where the use of a RaaS could have improved the overall example solution. Disclaimer: I'm not requesting stakeholders in my project nor am I delegating work. Any materials other than feedback, advice or directions will not be utilized.
